Collaborative commenting in a drawing tool

ABSTRACT

Methods and systems providing for collaborative commenting in a drawing tool are provided. One example method includes receiving a shape on a drawing canvas, and receiving a comment associated with the shape, the comment including a name of a commenting user. The method also includes receiving an indication of a movement of the shape from the first position to a second position, and, in response to the indication of the movement of the shape, automatically moving the comment closer to the second position of the shape. In some cases, the commenting user can be a user other than the user adding the shape to the document, and can be performed by a concurrent editor of the document.

RELATED APPLICATIONS

This application is related to co-pending U.S. patent application Ser. No. 13/294,943, titled “Coauthoring in a Drawing Tool,” filed on Nov. 11, 2011, which is hereby incorporated by reference in its entirety.

BACKGROUND

Computer-aided drawing tools are often used by design professionals to design a variety of systems, such as electrical diagrams, floor plans, business processes, program architectures, state machines, and other types of systems. Commenting in a drawing tool involves different considerations from those presented in other software in which commenting systems are provided, such as presentation software or word processing software. This is because, while in word processing or presentation software data is managed in a sequentially-organized document, in a drawing tool various features can be arranged in different orders within a particular page or set of pages.

Additionally, traditionally a smaller set of individuals has access to drawing tool software as compared to presentation or word processing software. While those individuals may not wish to purchase a full copy of drawing tool software, they may wish to be able to make comments on drawings that have been created by those who do have the drawing tool software. Currently, no mechanism exists for allowing such commenting to occur.

SUMMARY

In accordance with the following disclosure, the above and other problems are addressed by the following:

In one aspect, a computer-implemented method includes receiving a shape on a drawing canvas, and receiving a comment associated with the shape, the comment including a name of a commenting user. The method also includes receiving an indication of a movement of the shape from the first position to a second position, and, in response to the indication of the movement of the shape, automatically moving the comment closer to the second position of the shape.

In a second aspect, a computer-implemented method of managing comments in a drawing document is disclosed. The method includes receiving a shape on a drawing canvas, and receiving a first comment from a user, associated with the shape. The method also includes receiving a second comment from a user, the second comment associated with the drawing canvas. The method further includes displaying a first icon indicating the presence of the first comment alongside the shape, and displaying a second icon indicating the presence of the second comment on the drawing canvas.

In a third aspect, a system for facilitating collaborative commenting in a drawing tool is disclosed, and includes a drawing tool executable on the first client computing system, the drawing tool configured to access a drawing document stored at a server system and display the drawing document including a drawing canvas. The drawing tool is configured to receive a shape on the drawing canvas, the shape placed on the drawing canvas in a first position by a first user. The system further includes a second drawing tool executable on the second client computing system remote from the first client computing system, the second drawing tool configured to display the drawing document and receive a comment from a second user associated with the shape placed on the drawing canvas by the first user, wherein the first and second users concurrently access the drawing document from the server system.

This Summary is provided to introduce a selection of concepts, in a simplified form, that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used in any way to limit the scope of the claimed subject matter.

DETAILED DESCRIPTION

Various embodiments of the present disclosure will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the disclosure, which is limited only by the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments.

The logical operations of the various embodiments of the disclosure described herein are implemented as: (1) a sequence of computer implemented steps, operations, or procedures running on a programmable circuit within a computer, and/or (2) a sequence of computer implemented steps, operations, or procedures running on a programmable circuit within a directory system, database, or compiler.

Embodiments of the present invention are directed to methods, systems, and user interfaces configured to provide commenting features in a drawing, including commenting features capable of association with collaboratively-edited drawings. The systems and methods described herein improve collaboration among users accessing a drawing tool by allowing users to view and respond to other users' comments, associate comments with particular drawing objects in a drawing, and communicate comments among coauthors of a particular drawing. In certain embodiments discussed herein, the commenting features of the present disclosure can be provided in a drawing displayed in drawing tool, a web browser representation of a drawing, or a drawing viewer. By providing commenting features available in each of these tools, the systems and methods of the present disclosure allow collaboration among a wider range of individuals, including those not directly involved in the drawing development process, and therefore may not have a copy of the drawing tool software that would otherwise be used for such commenting.

In accordance with the present disclosure, the drawing document is referred to as “collaborative” to indicate that the drawing document can be commented on and edited by more than one user. In embodiments, the drawing document may or may not be coauthored, by which it is intended that two or more users can apply edits or comments associated with features in a drawing document concurrently, without edit locks included within the tool to prevent concurrent editing of a common object, group of objects, or canvas included in a drawing document. Additionally, it is recognized that, in the context of the present disclosure although some embodiments of systems and methods for managing commenting involve commenting features that may be used in a stand-alone computing system operating a drawing tool, web browser, or drawing viewer. As such, in those embodiments the commenting features are available in any of a variety of these types of systems, and do not require the presence of the drawing tool software to enable commenting.

Referring now to FIG. 1, an example of a networked arrangement 100 is illustrated in which commenting in a collaborative drawing document could take place. In the embodiment shown, the networked arrangement 100 includes a plurality of client devices 102 a-c (referred to collectively or individually as client devices 102), communicatively connected to a server device 104 by way of a network 106, such as the Internet. The client devices 102 generally each include some type of software allowing commenting of a drawing document, such as drawing tool software, such as VISIO® drawing and layout software provided by Microsoft Corporation of Redmond, Wash. Alternatively, one or more of the client devices 102 could include web browser software or a drawing viewer version of the drawing tool, in which editing capabilities may be limited. The server 104 can be any of a number of types of computing systems, and in certain embodiments includes collaborative software, such as SHAREPOINT® server software, also available from Microsoft Corporation.

In general the present disclosure is related to situations in which a particular drawing tool, web-browser drawing version, or drawing viewer allows comments to a drawing document, or various features within the drawing document. In some embodiments, the present disclosure contemplates a circumstance in which users of two different client devices 102 intend to access a particular drawing document stored on the server 104, either sequentially or concurrently. In the embodiment shown, client devices 102 a and 102 c have accessed a document 108, and are managing that document as local documents 108′, 108″ on those devices, respectively. As users of those respective client devices 102 a, 102 c edit or comment on the document retrieved from the server 104, the drawing document 108′, 108″ diverge. However, by synchronizing comments and other data across the two devices 102 a, 102 c (as well as other devices associated with coauthoring users) via the server 104, and by notifying the coauthoring users of edits made by other users, concurrent editing by coauthors can be managed. The present disclosure relates generally to addition of comments to such a document in collaborative fashion; generally, methods for managing coauthoring edits to the document (e.g. changes to the shapes included within such a drawing document) are discussed in copending U.S. application Ser. No. 13/294,943, entitled “Coauthoring in a Drawing Tool”, filed on Nov. 11, 2011, the disclosure of which is hereby incorporated by reference in its entirety.

In some embodiments described herein, the server 104 is configured to manage a list of users of client devices accessing the drawing document 108 for coauthoring and commenting purposes. In the example explained above, for example, the server 104 would include a list of users of devices 102 a, 102 c, but would not include a user of device 102 b in the list. The list of users associated with the drawing document can be used to share notifications of drawing modifications among current coauthors, including comments among those authors. Additionally, the list of users accessing the drawing document and list of comments included in the drawing document can include contact information, so the coauthoring users can contact each other with questions or concerns about ways to resolve any potential conflicts between edits applied by each user.

In general, to achieve conflict resolution and comment editing systems relative to a drawing object as described herein, maintenance of an original drawing is supported, as well as maintenance of the edited drawings of each coauthoring user to determine when and where such conflicts take place. As illustrated in FIG. 2, a system 200 for managing coauthoring in a drawing tool is shown, according to an example embodiment. The system 200 generally includes a server storage and synchronization area 202 interfaced with a local document cache 204, such as would be provided in the client-server arrangement illustrated between any of the client computing devices 102 and server 104 of FIG. 1.

In the embodiment shown, the system 200 includes a server storage area 206 in which a copy of a drawing can be stored. The server storage area 206 can be, in such embodiments, a database or server workflow management system, such as SHAREPOINT® server software, also available from Microsoft Corporation. A client 102 can retrieve a download copy 208 of the drawing from the server storage area 206. The download copy 208 corresponds to a latest copy available in the server storage area 206. To preserve the client's knowledge of the current state of the document as maintained in the server storage area 202, a base copy 210 is created from the download copy 208, and represents the copy of the download that occurred after the last successful merge of the client and server copies took place (as further discussed below). A working copy 212 is also created from the download copy 208, and is used for local editing/modification by a user. As a user edits the working copy 212 of the drawing, that user may wish to upload his/her changes back to the server to be saved. That user can select a “save” option within a drawing tool, which will in turn create an upload copy 214 of the drawing, which can be returned to the server storage area 206.

When the user of the client computing device 102 adds comments to a document, those comments can be included within a portion of the drawing document that is configured to be accessible within a variety of types of tools, including the drawing tool, a web browser, or a viewer tool. For example, the comments can be stored in and managed by metadata used to manage coauthoring features, as described in co-pending U.S. patent application Ser. No. 13/294,943, titled “Coauthoring in a Drawing Tool,” filed Nov. 11, 2011. Alternatively, the full document could be stored to include the comments. Although in the embodiment discussed in connection with FIG. 2 all portions of a drawing document may be downloaded to a client, in circumstances where the client device 102 only accesses the drawing document using a web browser or viewer, or only updates a comment in a drawing tool, only the portion of the document that illustrates the current visual display of shapes and a feature allowing commenting are provided, and only portions thereof that are updated with comments are required to be transmitted back to a server to be saved.

Referring now to FIGS. 3-4, methods for managing commenting among collaborative users are shown, according to embodiments of the present disclosure. The methods illustrated in FIGS. 3-4 generally can be performed at one or more client devices, such as any of devices 102 a-c of FIG. 1, or any stand-alone client device, such as a desktop, laptop, or mobile computing system, either connected to or disconnected from a server system or other computing system for at least a portion of the time the drawing document is edited or commented upon. Additionally, although aspects of the methods disclosed herein generally will involve certain editing steps to be performed using a drawing tool (e.g., direct editing of drawing shapes within a drawing document), other steps (e.g., adding or editing comments) can be performed using such a tool or a web viewer or other type of drawing viewer.

Referring to FIG. 3, a flowchart of a method 300 for commenting within a drawing is shown. In the embodiment shown, the method 300 includes receiving a shape on a drawing canvas of a drawing document (step 302). In connection with the present disclosure, receiving the shape on the drawing canvas generally occurs within a drawing tool, because editing of a drawing document directly typically involves use of desktop drawing tool software, rather than, for example, only a drawing viewer. The method also includes receiving a comment associated with the shape (step 304). The comment associated with the shape will generally include a name of a commenting user. If the same user added the shape and commented on the shape, that user's name will be associated with the shape. However, if the drawing document is transmitted between a first user and a second user after the shape has been placed on the drawing canvas and the second user inserts a comment into the drawing document in association with the shape. In various embodiments of the present disclosure, receiving a comment could occur, for example, in either a drawing tool or a drawing viewer, such as a client drawing viewer or web browser.

The method 300 also includes receiving an indication of movement of the shape from a first position to a second position, for example on the same drawing canvas, or sheet, or another canvas within the drawing document (step 306). This may occur, for example, when a user of a drawing tool opts to move a shape that has a comment previously associated with it. The method 300 includes, in response to the movement of the shape, automatically moving the comment closer to the second position of the shape (step 308).

Accordingly, as shapes are moved within a drawing document, comments associated with those shapes can be moved as well, to ensure clear graphical correspondence between shapes in a drawing document and comments associated with those shapes. Examples of user interfaces depicting drawing shapes and associated comments are described below in connection with FIGS. 5 and 16.

Furthermore, and in accordance with the general method illustrated in FIG. 3, it is understood that additional users besides the one who edited or created the drawing document can insert comments into that drawing document. As additional users insert comments into the drawing document associated with various drawing objects (e.g., shapes included on a drawing canvas or the drawing canvas itself), those users can have their names and/or contact information displayed in association with those elements on the drawing document. Additionally, users can serially add comments in response to each others' comments or on different aspects of the drawing document, as illustrated in further detail in the user interfaces of FIGS. 9-15 and 17-18.

Referring now to FIG. 4, a method 400 is described that provides for management of collaborative and coauthored comments, according to a possible embodiment. The method 400 generally involves receiving a shape on a drawing canvas (step 402); this generally corresponds to step 302 of FIG. 3. The method also includes, for example, receiving a first comment from a user, such that the comment is associated with the shape (step 404); this additionally corresponds to step 304 of FIG. 3. The method 400 also includes receiving a second comment from a user, which is associated with the drawing canvas (step 406). In some other embodiments, such comments could be considered comments that are not otherwise associated with any particular shape or other drawing object, but are associated with the drawing as a whole. In various embodiments, the second comment could be associated with the drawing canvas by the same user as the user applying a comment to a shape in step 404, or a different user who accesses the drawing document either concurrently with, before, or after the user who adds a comment in association with a shape. Additionally, as discussed above, the commenting received in either of steps 404 and 406 can occur within a drawing tool, web viewer, or desktop viewer.

In the embodiment shown, the method 400 optionally includes synchronizing the comments and/or edits made in steps 402-406 with a server version of the drawing document, for example in the circumstance where the drawing is stored on a server and managed as a document accessible to many users and capable of supporting coauthoring (step 408). During synchronization, the comments inserted into the document can be transmitted to a server for viewing by other client devices, and comments made by users of other client devices can be updated to the local drawing document as shown to the local user.

In various embodiments, the synchronization process of step 408 can occur in different ways. For example, synchronization may occur periodically or upon selection of a save operation within a drawing tool. If comments are added in a web browser or local viewer version of the drawing document, the viewer may include a prompt to receive a user indication that the comment has been entered (e.g., an “OK” button, or other user input element) to synchronize those comments with a server version of the drawing document. Additionally, for such viewer versions of the drawing document, the document itself may be updated, and the comments saved to a server version of the drawing document, if that user selects to update the viewed version of the drawing, for example by selecting to refresh the view presented in the browser or viewer.

The method 400 includes displaying a first icon in association with the shape (step 410), and displaying a second icon in association with the canvas (step 412). Generally, and as illustrated in FIG. 5, discussed below, as comments are added to a drawing document and associated with particular portions of the drawing document, icons can be added to the drawing document to indicate to users of that drawing document that the user, or a different user, has added a comment associated with that particular drawing element.

After comments are added to the drawing document, users accessing that drawing document have flexibility in the manner in which they interact with such comments. As such, in some embodiments, the systems disclosed herein can manage comments (step 414), for example by receiving edits from users regarding either their own comments or other users' comments, or by receiving feedback from users regarding comments (e.g., to reply to the comment or to indicate that the edit noted in the comment is completed). In various embodiments, and as illustrated in the Figures below, comments can be displayed and managed either within the drawing canvas display or in a separate comments panel, selectable by a user. Furthermore, in various embodiments, the comment itself may or may not be displayed at all times; rather, a user may elect to hover over or select the icon displayed in association with the drawing object to which the comment is associated to enable the comment to be displayed.

Referring now to FIG. 5, an example schematic of a user interface 500 of a drawing tool is shown, according to a possible embodiment. In the embodiment shown, the user interface 500 supports collaborative commenting, in conjunction with the principles of the present disclosure. Additionally, the user interface 500 represents an interface that supports coauthoring of a drawing document, including use of notification features such as are described in co-pending U.S. patent application Ser. No. 13/294,943, titled “Coauthoring in a Drawing Tool,” filed on Nov. 11, 2011, the disclosure of which is hereby incorporated by reference in its entirety.

In the embodiment shown, the user interface 500 includes a drawing panel 502 displaying one or more drawing canvases incorporated into a drawing document, and a side panel 504 in which shapes can be displayed for selection and inclusion into the drawing. The user interface also includes a toolbar 506 along a bottom edge of the drawing panel 502 and side panel 504, as well as a ribbon panel 508 along a top edge of the user interface. Optionally, the user interface also includes a commenting panel 510 along a right side of the drawing panel 502.

Within the drawing panel 502, a user may place and edit a variety of types of shapes 512 on a drawing canvas 514, using tools depicted in the side panel 504 and ribbon panel 508, as is known in the art. In the embodiment shown, a flowchart including a variety of drawing shapes 512 is shown. Associated with one or more of the shapes and optionally as associated with the drawing canvas as well, a notification feature 516 can be depicted, with which one or more recent changes or comments are noted. Each notification feature 516 can include one or more icons 518, including an icon intended to indicate the existence of a comment. In the embodiment shown, two drawing shapes 512 a and 512 b are depicted as associated with comments; the first drawing shape 512 a is associated with a first notification feature 516 a, including an icon 518 a labeled as “in-canvas comment tag.” A commenting dialog 520 is also displayed in association with the icon 518 a, and the drawing shape 512 a, such that if the drawing shape 512 a is moved, the commenting dialog 520 will move as well, to be placed in proximity to the drawing shape, as noted above in FIG. 3. Additional details regarding features of the commenting dialog 520 are discussed below, in connection with FIGS. 9-11.

The second drawing shape 512 b is associated with a second notification feature 516 b, which includes a number of icons 518 b-d, representing both the existence of a comment and the existence of coauthoring changes, either before or after a most recent save made by a coauthor, as described in co-pending U.S. patent application Ser. No. 13/294,943, titled “Coauthoring in a Drawings Tool,” filed Nov. 11, 2011 previously listed. Additionally, a third commenting icon 516 e is displayed in a top lefthand corner of the drawing canvas 514, indicating a comment that was made that relates to the drawing overall.

In the toolbar 506, an indicator 522 includes an indication of a number of users currently accessing the document, for example in a coauthoring embodiment of the drawing tool. Other notifications could be included within the toolbar 506 as well. Additionally, the ribbon panel 508 includes a number of tabs allowing a user to edit, save, or modify the drawing. In some embodiments, the ribbon panel 508 can include a commenting ribbon useable to track and add, edit, or delete comments. An example of a commenting ribbon is illustrated in FIG. 6.

The commenting panel 510 includes a cumulative list of the comments included in a drawing document, ordered by date and time added, as well as by page on which those comments are located. The commenting panel 510 can also be used to view, edit, sort, add, or delete comments associated with the drawing document, and includes information associated with the user making the comment. Additional details regarding the commenting panel 510 are discussed below in connection with FIGS. 12-15.

Although in the embodiment shown both the commenting panel 510 and a commenting dialog 520 are illustrated, in typical embodiments comments will be illustrated in one of these two arrangements, to avoid duplication of comments within the user interface. Generally, one of the commenting panel 510 and commenting dialog 520 arrangements is selectable by a user, to preserve space within the user interface.

Referring now to FIG. 6, an example schematic of a commenting ribbon 600 useable within the user interface 500 of FIG. 5 is shown. The commenting ribbon 600 includes a new comment button 602, a commenting pane button 604, and comment review buttons 606 a-d. The new comment button 602 allows a user to insert a comment into the drawing, either with respect to a currently selected drawing shape or the drawing canvas overall. The commenting pane button 604 allows the user to select or deselect use of a commenting panel or commenting dialogs displayed in the drawing canvas, such as is shown in the commenting panel 510 and commenting dialog 520 of FIG. 5.

The comment review buttons 606 a-d allow a user to edit, delete, or navigate among comments within the drawing. Additionally an ink button 608 allows a user to “handwrite” on the drawing, for example to insert edits that can be included on the drawing.

Referring now to FIGS. 7-8, example notification features including commenting icons are illustrated, depicting an indication that a comment exists that is associated with the depicted shape. In general, the notification features illustrated in these figures are affiliated with specific drawing objects, indicating that the drawing object is in use or is otherwise edited by a user. FIGS. 7-8 generally illustrate a drawing object with an associated notification feature 702. The notification feature 702, in each example, includes a plurality of fields, including an update notification field 704, a coauthor notification field 706, and a comment notification field 708. The update notification field 704 and coauthor notification field 706 generally relate to notifying coauthors of changes that have recently occurred in the drawing, and are generally managed within the drawing tool. The comment notification field 708 indicates the existence of a comment in association with the shape or drawing canvas. FIGS. 7-8 also illustrate positioning of the notification feature 702 relative to different drawing objects. In FIG. 7, the notification feature 702 is presented along a top right corner of a drawing object 700. In FIG. 8, the notification feature 702 is presented in association with a group object 800 (illustrated as a cubicle). In this arrangement, the group object has been previously grouped by the drawing tool; accordingly any change to a sub-element of the object 800 is propagated as a change to the object overall, and the notification feature 702 is updated accordingly.

Referring now to FIGS. 9-11, details regarding a commenting dialog 520 are illustrated. In the embodiment shown in FIG. 9, the commenting dialog 520 includes a listing of comments 900 that a user can scroll through, as well as an add comment button 902 that can be used to add a new comment associated with the currently-selected shape or canvas. Generally, each comment in the commenting dialog includes a collection of rich text data, and is typically of limited length (e.g., up to about 64 k bytes in size). Additionally, each comment can be associated with a commenter's user profile, including a name and image of the user, as well as a date on which the user made the comment.

FIG. 10 illustrates the commenting dialog 520 with a comment 1000 selected. In this Figure, the comment 1000 has associated with it a delete option 1002, a completed option 1004, and a reply option 1006. The delete option 1002 allows a user to remove the comment, while the completed option 1004 allows the user to indicate that the comment has been addressed, and will, if selected, cause the comment to be “grayed out” or inactive within the dialog 520. The reply option 1006 allows a user to create a comment that is in specific reply to the selected comment.

FIG. 11 illustrates relative location of the commenting dialog 520 to a drawing shape 1100. As illustrated, the drawing shape 1100 has a notification feature 518 and associated icons 518, including a commenting icon indicating that comments exist associated with the drawing shape 1100. The commenting dialog 520 can appear, for example, upon selection of the commenting icon. Additionally, when the drawing shape 1100 is placed along an edge of a drawing panel, the commenting dialog 520 can be placed in other locations relative to the shape to which it is associated.

In each of FIGS. 9-11, each comment includes an identification of a user, such that the user can be viewed and selected to identify contact information for that user. As such, a commenting user can be identified and contacted for clarification, as determined to be necessary by the user.

Referring to FIGS. 12-14, analogous commenting user interface regions are shown, illustrating features of a commenting panel 510. The commenting panel 510 includes generally analogous features to and can be used in substitute for the commenting dialog 520, as described above. In the embodiment shown in FIG. 12, the commenting panel 510 displays all of the comments associated with a particular drawing document, including comments associated with one or more drawing shapes. In the embodiment shown, the commenting panel 510 includes a header region that includes navigation arrows 1200 allowing a user to step through the comments in order, as well as a filtering drop-down box 1202 that allows a user to filter the comments by page, commenter, thread, or other order or criteria. The commenting panel 510 also includes add and delete comment options 1204, 1206. In FIG. 13, the commenting panel 510 is unsorted, illustrating that comments across multiple drawing canvases can be included and traversed using the panel. As discussed above with respect to the commenting ribbon 520, when a comment is selected a delete option 1302, a completed option 1304, and a reply option 1306 are displayed. In FIGS. 14-15, the commenting panel 510 is sorted by thread, with one of the comments 1400 “grayed out” because a user had selected an associated completed option 1304. Each of the comments is otherwise as discussed above in connection with FIGS. 9-11.

Referring now to FIGS. 5-15 generally, it is recognized that, when using a drawing tool as depicted, coauthors may also comment on a particular drawing document, and therefore it is possible that one user may be editing a comment while another user is intending to delete that comment. When one author deletes a comment another author is editing or two authors edit a comment simultaneously, both sets of changes will be persisted as a separate comment rather than merging or losing changes. Each comment will contain the personal information for the most recent user. Additionally, if the shape to which a comment is associated is deleted, the comment and all other related comments are deleted as well. Otherwise, as conflicts occur, they are typically resolved on a “last edit wins” basis.

Referring now to FIGS. 16-18, example user interface features associated with a “viewer” version of the document are shown, such as might be available in a desktop drawing viewer or web page drawing viewer tool, according to an example embodiment. In the embodiment shown in FIG. 16, a user interface 1600 includes a separate drawing frame 1602 and comment frame 1604, allowing the reviewing user to view the drawing in the drawing frame 1602, while allowing the reviewer to either view or edit comments in the comment frame 1604.

The term computer readable media as used herein includes both storage media and communication media.

This embodiment of system 2002 is shown with two types of notification output devices; light emitting diode (LED) 2020 that can be used to provide visual notifications and an audio interface 2074 that can be used with speaker 2025 to provide audio notifications. These devices may be directly coupled to power supply 2070 so that when activated, they remain on for a duration dictated by the notification mechanism even though processor 2060 and other components might shut down for conserving battery power. LED 2020 may be programmed to remain on indefinitely until the user takes action to indicate the powered-on status of the device. Audio interface 2074 is used to provide audible signals to and receive audible signals from the user. For example, in addition to being coupled to speaker 2025, audio interface 2074 may also be coupled to a microphone to receive audible input, such as to facilitate a telephone conversation. In accordance with embodiments of the present invention, the microphone may also serve as an audio sensor to facilitate control of notifications, as will be described below. System 2002 may further include video interface 2076 that enables an operation of on-board camera 2030 to record still images, video stream, and the like.

A mobile computing device implementing system 2002 may have additional features or functionality. For example, the device may also include additional data storage devices (removable and/or non-removable) such as, magnetic disks, optical disks, or tape. Such additional storage is illustrated in FIG. 20B by storage 2068. Computer storage media may include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data.

Data/information generated or captured by the device 2000 and stored via the system 2002 may be stored locally on the device 2000, as described above, or the data may be stored on any number of storage media that may be accessed by the device via the radio 2072 or via a wired connection between the device 2000 and a separate computing device associated with the device 2000, for example, a server computer in a distributed computing network, such as the Internet. As should be appreciated such data/information may be accessed via the device 2000 via the radio 2072 or via a distributed computing network. Similarly, such data/information may be readily transferred between computing devices for storage and use according to well-known data/information transfer and storage means, including electronic mail and collaborative data/information sharing systems.

FIG. 21 illustrates a system architecture for providing the host application 1920 to one or more client devices, as described above.
